The feud between Donald Trump and Elizabeth Warren continues, after Trump called Warren “Pocahontas” during a New York Times interview. In an interview with the New York Times, columnist Maureen Dowd wrote that when she “asked if he had been chided by any Republicans for his Twitter feud with Elizabeth Warren, Trump replied, ‘You mean Pocahontas?’” Trump’s insult references Warren’s claim to have Native American ancestry.

The feud began in March, after Trump was declared the presumptive nominee. Warren took to Facebook to write a post calling Trump a “bully” and “a loser.”

“Trump seems to know he’s a loser. His embarrassing insecurities are on parade: petty bullying, attacks on women, cheap racism, and flagrant narcissism. But just because Trump is a loser everywhere else doesn’t mean he’ll lose this election. People have been underestimating his campaign for nearly a year – and it’s time to wake up,” Warren wrote on Facebook.

The pair then took the fight to Twitter, continuing to sling insults at each other less than a week later. Trump called Warren a “flunky” on Twitter and referred to the Massachusetts Senator as, “Goofy Elizabeth Warren.”

Warren shot back calling Trump “a bully” who “spews insults and lies.” He then called her a “fraud” who is “weak and ineffective” and “not Native American.”

The Massachusetts Senator seemed unimpressed by Trump’s reaction to her post. “I called out @realDonaldTrump on Tuesday. 45 million saw it. He's so confident about his 'counter punch' he waited until Friday night. Lame.” Warren wrote on Twitter. She added that in order to defeat a bully, you need to stand your ground. “But here's the thing. You can beat a bully -- not by tucking tail and running, but by holding your ground,” Warren tweeted.

I hope corrupt Hillary Clinton chooses goofy Elizabeth Warren as her running mate. I will defeat them both.
